Background: Electronic portal imaging devices (EPIDs) play an important role in radia on therapy portal imaging, geometric and dosimetric verifica ons. A successful u liza on of EPIDs for imaging and dosimetric purposes requires a reliable quality control process rou ne to be carried out regularly. In this study, two in‐house phantoms were developed and analyzed for implementa on in a quality a...

The antigenic region (residues 109 to 160) of classical swine fever virus (CSFV) protein E(rns) and the N-terminal antigenic region (residues 1 to 136) of protein E2 were constructed in the form of a fused, chimeric protein, C21E(rns)E2, for use as an enzyme-linked immunosorbent assay (ELISA) antigen for the serodiagnosis of CSFV infection. Tested with 238 negative-field (CSFV-free) sera from C...

Plasmacytoid dendritic cells (pDC) have been shown to efficiently sense HCV- or HIV-infected cells, using a virion-free pathway. Here, we demonstrate for classical swine fever virus, a member of the Flaviviridae, that this process is much more efficient in terms of interferon-alpha induction when compared to direct stimulation by virus particles. By employment of virus replicon particles or inf...

e observation that parallel processing inevitably runs into issues managing data movement is hardly new. e old joke “a supercomputer is an expensive device that transforms a compute-bound problem into an I/Obound problem” now has a new variant: “a manycore processor is a device that transforms a compute-bound problem into a memory bound problem.” As we enter the multicore and manycore era, data...

cigs as a nico ne prod‐ uct that should be taxed for reasons of symmetry: if tobacco is heavily taxed, then other nico ne‐delivering items should be taxed like‐ wise. Poli cians of eve‐ ry stripe clearly wish to avoid being seen as en‐ couraging nico ne con‐ sump on. However, according to many spe‐ cialists, the poten al benefits of e‐cigs in the fight against smoking may be quite significant. ...

Classical swine fever (CSF), also known as hog cholera is an long-standing disease, being described as early as 1833, in Ohio USA (1). CSF continues be of importance presently (2). The disease causes major damage to the pig populations in the Chinese provinces and in other countries worldwide (3). CSF is a highly contagious disease that mainly spreads by contact between live pigs or by feeding ...

BACKGROUND Rare diseases pose many research challenges specific to their scarcity. Advances in potential therapies have made it more important than ever to be able to adequately identify not only patients with particular genotypes (via patient registries) but also the medical professionals who provide care for them at particular specialist centres of expertise and who may be competent to partic...

A .—From 1994 to 2003, I annually surveyed terrestrial insectivorous birds in a 100-ha plot within continuous rainforest near Manaus, Brazil. I used spot-map registrations and radiotagged birds to estimate territory size and density on the plot for 13 species. As in the few previous studies of Amazonian birds, territory sizes were large (mean = 13.0 ha) and densities were low (mean = 3.4 pairs ...
